INSOLE.

Specication of Letters Patent.

Application filed May 1, 1911. Serial No. 624.322.

To all whom it may concern:

Be it known that l, Geenen L. Pnennn, of Lynn, in the county of Essex and State of Massachusetts, have invented certain new and useful improvements in' Insoles, or" which the following a specification.

This invention relates to insoles composed ot a plurality bf layersof ditl'erent materials. i

A common form of insole now in extensire use is composed of a `layer of woven material and layer of leather, the two layers being attached one to another by cement. rhe ylayer of woven material is creased to form' a stitch-receiving rib, and it is customary to inclose in the crease a strip of suitable material, suchas' stout cord, for the purpose of reinforcing the stitch-receiving rib. vAn insole composed of layers cemented together iii this Way is oftentimes inetlicient, because a relatively slight .strain is sutlicient to pull apart the layers which are joined solely by cement.-

The object of the present invention is to provide a composite insole ot' which the layers are composed ot' Vmaterials which may be united and which when united Will be substantially inseparable, however great may be the strain tending apart.

The essential elements of an insole constructed in accordance with this invention are: a layer of textile `material and a layer or" Celluloid. The textile material is pro- `vided with the usual crease to form the stitch-receiving rib, and the Celluloid laid against the opposite side oli-the textile material with relation to the rib is interlocked with the bers ot' the textile material by subjecting it to any suitable solvent and by pressing the layers together while the celluloid is somewhat soft and plastic. A reinforcing strip of fibrous material may or may not be placed in the crease of the textile material, as desired. It such reint'orcing strip is used, it is directly united with the Celluloid by the fsame process which unites the celluloid with the layer ot textile material. The reinforcing stri is -thcrefore not only held in place by tie layer ot textile material, but is held independently' thereofl by the celluloid itself. lVhcn the Celluloid hardens after being lpressed into the spaces between the fibers of the textile material', the layers are so iirmly interto` pull them The same reference characters indicatev the same parts wherever they occur.

The layer oi textile material'is indicated at l0, and the layer ot celluloid is indicated at 1l. The celluloid is interloclted with the textile material asrepresented by the sectional views.` rlhe textilematerial is creased to form a stitch-receiving ribv l2. As shown by Figs. 2 and .4, a reinforcing strip 13 is laid in' the crease of the rib. The Celluloid ll is directly interlocked with the tibersof the strip 13. An insole comprising the foregoing elements assembled in the -manner. described is complete tor some kinds of foot-wear. the layer of Celluloid being sut'liciently flexible to all'ord comfort. to the wearer and being a sulticient soclrlining.

To the foregoing elements may be added,

when desired, a shank stitl'ening member such as that indicated at lll in Fig. 3. vVhen a stitfening member is used,'it is desirable to add also another layer 15 of material suitable tor a sock lining. q"Woven material is suitable tor this purpose. When the member 14 and layer l5 areto be used, the member 1.4 is interposed between the celluloid and the'layerrl. The layer l5 directly engages the celluloid in the forepart: ot the sole and is interlocked with the Celluloid in the same manner `as the layer lt). lhc (zelluloid may also be interlocked with the tib'crs of the stittening member 14 by applying a suitable solvent to the celluloid before pressing the stitt'ening member against it. A coating l'ot cement is used to unite' the stitfening member le. and the y, lining l5.

. `An insole. composed of the aforesaid ele- Iments ,is vnot only strong, but is waterproof and 'moisture-proof. The layer of Celluloid. intervening between the foototwthe wearer 'and the leather sole not only prevents the admfssion off moisture frena Wheut, but usulates alle leathe sole from the foot s0 tha perspraien from the :loot will nel; reach the leathe sole and cause 'otng of the leather and the usual oder v caused therebyE l. claimh l.. le an article of manufacture, an im sole comprising a layer of textile material having a crease, a strip of brous material in said crease, and a layer of Celluloid -interlocled with. said layer Gf textile material and with Said strip;

In testimony whereof l have axecl my signature, in presence of two Witnesses.
